Miami Dolphins defensive end Andre Branch celebrates after the Dolphins stopped the San Francisco 49ers from scoring on the last play of the game and forcing overtime Sunday at Hard Rock Stadium in Miami Gardens.

Ryan Tannehill, who completed 20-of-30 passes for 285 yards and three touchdowns, has never played better during his five-year NFL career. Not only is he delivering big plays, but he’s also evading sacks and turning them into respectable gains for the offense. Getting tight end Dion Sims, who caught four passes for 53 yards, more involved will allow the offense to continue its evolution.

The Miami Dolphins are approaching uncharted waters. With their 31-24 victory over the San Francisco 49ers on Sunday, the Dolphins, who are riding a six-game winning streak, are in possession of the AFC’s final wild-card spot, which means the team controls its own fate with five games left in the regular season. Another win and the Dolphins (7-4) are not only one victory closer to producing the franchise’s first winning season since 2008, but Miami would match a seven-game winning streak it had in 1985. These Dolphins have already shown the franchise’s culture is changing, but can they finish strong? That is what this stretch of December games will tell us. Here is the Sun Sentinel's report card, evaluating how the Dolphins performed against the 49ers:
